The mechanism for the gas-phase reaction between NO and H₂ is thought to be NO(g) + NO(g) = N₂O2(g) (rapid equilibrium) N₂O2(g) + H₂(g) → N₂O(g) + H₂O(g) (slow) N₂O(g) + H₂ ₂(g) + (fast) What rate law is predicted by this mechanism when the rate-determining step approximation is used? (The rate constant in the rate laws below is the effective rate constant.) rate = k[NO][H₂] rate = K[NO]²[H₂] rate = k[NO]² rate = k[NO][N₂O₂][H₂] rate = k[NO][H₂]²
